CEP’s Run Crew Compression Socks 4.0 incorporate all the same benefits of the 3.0 Socks but with improved technology for better performance. Targeted compression in the arch and ankle increases blood circulation and provide support to prevent injury, reduce swelling, and alleviate pain from Plantar Fasciitis and the Achilles tendon. The versatile height pairs with any style shoe or outfit. Innovative air channels in the footbed and ventilation zones in the toe add optimal breathability and ultimate comfort. Take every stride in confidence thanks to anatomically designed padding along the footbed that absorbs shock to minimize fatigue and reduce strain on joints.
